GEORGE H. ALLEN, OF PALO ALTO, CALIFORNIA.

OIL-BURNER.

Application filed May 20", 1910.

To all whom it mag concern: v

Be it known that I, GEORGE ALLEN, residing in the city ofaPalo Alto, in the county of Santa Clara, State of California, and a citizen of the United States, have invented a new and useful Improvement in Oil-Burners, of which the following is a specification, reference being hereby made to theaccompanying drawings, forming a part hereof.

My invention relates to an oil burner of the type intended to be fitted to an ordinary stove or furnace and in which the oil is converted into gas before coming into contact with the flame.

The primary object of my invention is to provide an oil burner which shall be capable of burning a heavy oil in a satisfactory and efficient manner. I accomplish this object by the manner in which the gas is generated from the oil and the gas and air mixed and then brought to the flame.

The invention will be more fully explained hereinafter with reference to the accompanying drawings in which it is illustrated, and in which Figure 1 is a sectional side elevation of a burner embodying the features of my invention. Fig. 2 is a plan view of the burner with a portion broken away to show the inside more clearly. Fig. 3 is a separate view of the door cover. Fig. 4c is a separate view of the heat conducting plate.

A is the body of the burner and B is a passage forming a part of the body and serves as an air duct and mixing chamber.

0 is a removable heat conducting plate which fits inside "the body A, theedge resting upon a ledge, thus forming the generating chamber D. The edge of the plate C is notched as shown in Fig. 4 for the purpose of establishing communication between chambers B and D.

E is a hole through which oil is admitted into the generating chamber.

F is a flange or plate of suitable size and shape and may be made integral with the body A. I prefer to make F a separate plate and attach it to lugs G G of the body by means of screws or bolts H H.

I is a door cover which is hung on the hook J of plate F on the front of the burner for the purpose of closing all apertures in the front of the burner except the two entrances of the air duct or mixing chamber B.

K is a knob on the cover I for convenience in manipulating.

Specification of Letters Patent.

door in front of the burner.

Serial No. 562,541.

M is a lug on plate C and servesas a handle. y

' L L are two beveled strips forming a part of plate C. These strips register with the beveled inner wall of thechamber'B to form a narrowslit 0 through which the gas and air issue to be burned.

N is the front wall of the burner.

In operation the burner .isfitted into the end or side of the tire box of the stove or furnace by means of the plate F which is fastened to the wall of the fire box. In Fig. 1 that portion on the right of plate F projects intov the stove or furnace and that on the left remains outside. The fire box should be rendered quite air tight by the applica tion of fire clay in order that whatever air enters the fire box may come through the air duct of the burner.

The generating plate is in its place inside the burner and the door cover I is removed. Oil is then admitted into the burner until it fills the chamber D and slightly overflows the top of plate C when it is shut off. The oil in the burner is ignited by means of a lighted match or torch applied through the After the oil has caught fire the door is closed by cover I. The products of combustion passing up the stove pipe, cause a draft of air to be drawn through the mixing chamber of the burner into the flame which then burns more briskly. The plate C becomes heated by the fire and in turn heats the oil in chamber D.

In a very short time the oil becomes so hot that it is gasified and in such gaseous state flows into the mixing chamber. Upon entering the chamber B, the gas becomes mixed with the stream of air which is flowing through. This mixture is the more thorough because the streams of air and gas come together nearly at right angles causing eddies to be formed in chamber B. The air and gas together issue through the annular slit 0 and are burned. Before the oil in the generating chamber is dissipated, the inlet valve is turned on and the fire continues to burn with no more attention. In a few minutes after the fire is started the generating plate C and the inner wall of the chamber B become so hot and the mixture is so raised in temperature that an exceedingly clear and efficient flame results. The fire is extinguished simply by shutting off the inlet valve.

Having thus described the nature and ob jects of my invention and the manner of its operation, what I claim as new and desire to secure by Letters Patent is,

1. An oil burner comprising a flat bottomed bowl having a straight front wall and side and rear walls, said side Walls and rear wall having an inwardly and downwardly arched extension spaced from the bottom and from the front Wall and forming a mixing chamber, an oil inlet in thebottom of the bowl, a shelf around the side and rear .walls withinthe bowl, and anotched plate resting on said shelf.

2. An oil burner comprising a flat bottorned bowl having a straight front wall and side and rear walls and also havingan ing two inclined vstrips projecting from its upper surface, and said extension being cut away adjacent said strips to form therewith discharge openings.
